Paper Abstract

Since 1989, 42 cases with low anal fistula were operated with laser and ordinary methods respectively. During the operation, secreted or charred tissues were extracted from the surface of the wound for bacteria culture. Experimental group (laser method): no bacteria were found in 24 cases operated by laser method. Control group (ordinary method): bacterial were found in 16 out of 18 cases operated by ordinary methods. The results of two different group showed that they had statistical difference for P < 0.001. So, CO2 laser is proved to be a definitely practical tool in surgical use for its bacteria killing power. While the anal fistula were operated by the laser, the neurotic carboatomic tissue can block blood vessel and prevent infection from spreading. The high temperature produced by the carboatomic action have enough ability to kill directly the bacteria living in the anal fistula.
